Notes:

• Trial version doesn't work on a VM/RDP/VPS. You have to try it on a dedicated computer, but the full version works on VM or any Windows-based machine.
•  All add-ons will be included automatically in the trial version of "Web Traffic Generator" app, but each one requires a separated license when you buy.
•  All what you need to activate your trial version is only a valid email address to receive the activation code from our server.
•  Changing your system proxy (your IP) during the installation process could establish an insecure connection with our server which denies our email system from sending the activation code.
